When, for example, a company is sending SaaS account setup email templates, email authentication blocks harmful uses of emails such as phishing.

However, to keep the user authenticated, it delegates some authentication responsibility to the client and requires them to sign a token with every request. This method is arguably the most straightforward and widely used currently. ![]() Many of today's tutorials will use JSON Web Tokens for token-based authentication (JWTs). Let's speak about login options briefly before we get started. While Node.js can also be used for building chatbots, it’s mostly popular for traditional websites and back-end API services. A broad range of mechanisms supports authentication via username and password, Facebook, Twitter, and other methods. The Passport may be easily integrated into any Express-based online application because of its flexibility and modularity. Passport is a Node.js authentication middleware. What is Passport.js, and how does it work? Please refer to this instruction if you're trying to install authentication using Facebook or GitHub. ![]() This tutorial will show you how to utilize Passport with a MongoDB backend to perform local authentication (that is, signing in with a username and password). Fortunately, there's a middleware called Passport that can be inserted into any Express-based web application to provide authentication procedures in only a few keystrokes for people building Node apps. A login system is a specific need when developing a web app to authenticate themselves before accessing protected views or resources. ![]()
